C400 Underground Crawler Mounted
The C400 Underground is a compact and versatile diamond core drilling rig specifically designed for underground mineral exploration.
Its drilling system is powered by an electric power unit, providing efficient, reliable and low-emission operation in underground working environments. For independent mobility between drilling locations, the rig is equipped with a crawler system driven by a dedicated diesel engine.
This combination of electric drilling power and diesel-powered crawler mobility allows the C400 Underground to deliver high drilling performance while maintaining the flexibility required for demanding underground operations.
Its compact configuration, robust construction and crawler-mounted design make it particularly suitable for mines where working space, mobility and operational efficiency are critical.
